本文旨在研究到目前为止前人对稀土氨氮废水处理技术的进展情况,尽管稀土氨氮废水的处理方法颇多,然而不是处理成本太高就是对水质的要求太苛刻,用于实践不太乐观;我们采用混合处理稀土氨氮废水的方法将减少处理成本,增强处理效果,如：化学沉淀＋吹脱,吹脱＋吸附等;另外,处理稀土氨氮废水要注意回收氨氮副产品,以抵消处理成本,达到清洁生产的目的。

We aim to research the advances in rare earth ammonia wastewater treatment technology so far as we can know.A lot of methodscould to be used in the treatment at present,however,neither the high costs or high quality requirements to the wastewater.it＇s not reasonable to use in the industrial production.We first use the mixed methods to deal with the rare earth ammonia wastewater,it＇s able to reduce the cost of processing and increase the effect.The methods were：chemical precipitation＋stripping,stripping＋adsorption and other ways.Futhermore,it＇s necessary to recovery the secondary product of ammonia nitrogen to offset the cost and protect the environment in the treatment process.
